Benefits of technology

[0004]An objective of the present invention is to provide a simpler arrangement for securing flexible two dimensional material such as mesh or screening material to engagement means including perimeter frames formed therefrom and to automatically stretch such material during the fitting process. Conveniently the engagements may be extruded from a plastics material or a light weight metal including but not limited to aluminium or aluminium alloys.

Problems solved by technology

While the retention method works satisfactorily, installation processes are somewhat time consuming.

Embodiment Construction

[0021]Referring to the drawings, FIG. 1 illustrates an extruded elongate section 10, which may be formed into a frame an engagement member capable of being used as is or assembled to form. The section 10 is conveniently formed in one piece with a first part 11 and a second part 12 connected by a plastics material hinge line 13. The first part 11 includes a longitudinally extending wall formation 14 that is complementary in shape to an elongate groove 15 formed in the second part 12 wherein in a first position, the wall formation 14 can be fully removed from the groove 15 (FIG. 1) or in a second position, the wall formation 14 can be fully engaged in the groove 15 (FIGS. 5, 6). Movement of the first part 11 between the aforesaid positions occurs by pivoting the first part 11 relative to the second part 12 about the hinge line 13. While a one piece construction as illustrated in the drawings is preferred, it is equally possible to make the two parts 11, 12 individually or as separate ...

Abstract

A screen structure consists of a flexible screen mesh material retained in a plurality of edge engagement members forming a perimeter frame for the screen structure. Each of the engagement members is formed by a first part joined to a second part by a hinge structure. The first part has a wall formation extending longitudinally along and laterally therefrom. The wall formation is engagable in a complementary shaped groove to retain an edge region of the screen mesh material in the groove. Both of the wall formation and the groove are inclined in an outward direction when the wall formation is engaged in the groove.

Description

FIELD OF THE INVENTION[0001]The present invention relates to improvements in products consisting of an outer, at least semi-rigid, perimeter frame with a flexible two dimensional material secured to and spanning an open space within the perimeter frame.BACKGROUND OF THE INVENTION[0002]One major application is the retention of mesh or screen material to a perimeter frame to form an insect screen for windows or doors, however, while the invention will be described hereafter with regard to this application, it will be appreciated that many other applications are equally possible including, for example, the securing of edge regions of shade cloth, mesh or similar materials. Conventionally, fly wire mesh or similar screening material is secured to the perimeter frame, typically an extruded aluminium rectangular section assembled at corners, by providing a groove surrounding the opening to be spanned by the screening material. One edge of the screening material is secured by positioning s...
